Diego Manfredi receveid the Laurea degree in Materials Engineering in 2003 and the Ph.D. degree in Materials Science and Technology in 2008, both at Politecnico di Torino. From January 2008, he worked with a 2-year post-doc fellowship in Materials Science and Chemical Engineering Department at Politecnico di Torino. Since January 2010 he joined IIT in the Center for Space Human Robotics, now Center for Sustainable Future Technologies.
His research activity is focused on the development of Additive Manufacturing (AM) technologies to fabricate structural and functional components like wave-guide filters for satellite-telecommunications, compact heat exchangers, heat sinks, hydraulic manifolds for robotic applications.
In particular the focus is on:
- develop a better understanding of the main physics phenomena involved in the Laser Powder Bed Fusion process (temperature gradients, powder-laser interaction time, etc..)
- study the effects of extremly rapid melting and subsequent cooling of the LPBF technology on the microstructure of the metal alloys processed through it
- create open architectures and structures like cellular, lattice and foams structures with high strenght Al alloys
2017-2019 PROGETTO REGIONALE STAMP “Sviluppo Tecnologico dell’Additive Manufacturing in Piemonte”, inside the Technological Platform “FABBRICA INTELLIGENTE”. IIT is involved in the fabrication of end-users demonstrators in different alloys by Laser Powder Bed Fusion process, and in the development of new alloys for the same process.
